"peak" means: peak? The peak period is when the electricity consumption is high, with many users and large electricity consumption.
"Valley" means: the valley is the night valley, and there will be redundant energy in the power grid, and the increase in frequency will also cause imbalance, resulting in the loss of economy and rationality of the power supply system. This period usually appears from 9 pm to 7 am.
The relationship between them is: total = sharp+peak+flat+valley.
Extended data:
In addition to the metering function of the basic electricity consumption of traditional watt-hour meters, smart meters also have intelligent functions such as bidirectional multi-rate metering function, user control function, bidirectional data communication function of various data transmission modes, and anti-theft function in order to adapt to the use of smart grids and new energy sources.
The ladder electricity price of residential electricity refers to dividing the daily electricity consumption of residential electricity users into several grades, and implementing a lower electricity price for the basic electricity demand part and a higher electricity price for the electricity exceeding the basic demand.
The electricity price level can be divided into 3-6 grades. The first step is base electricity, and the electricity price per kilowatt hour is also low, in order to ensure that low-income residents can get basic living electricity. # The electricity price of the second step is higher than that of the first step. According to the reasonable price level of cost+profit+tax. In addition to the reasonable electricity price level, the third step and above consider the internal proportion of external costs, reflecting the scarcity of resources. Higher steps can be priced.
